Class MicroEJMessageLite

  • public abstract class MicroEJMessageLite
extends java.lang.Object
    Base class for MicroEJ-generated protobuf messages.

    Replaces GeneratedMessageLite for environments without java.lang.reflect. Generated message classes extend this and provide inline writeTo, mergeFrom, and getSerializedSize implementations — no schema engine or reflection needed.

    Supports proto2 extensions via FieldSet and ExtensionRegistryLite.

                                   throws java.io.IOException
        Parses an unknown field during mergeFrom and stores it for round-trip preservation.
        Parameters:
        tag - the field tag that was not recognized
        input - the input stream positioned after the tag
        Returns:
        false if the tag is an end-group marker, true otherwise
